ATTORNEY EDWARD KENNEDY, or NEW YORK, NQY,

iE sTI No DEV CE Eon WATER SYSTEMS.

in Testing Devices for Water Systems, of

which the following is a specification. I The present 111VeIlt1OIl' relates to mprovements in testing devlces for water systems,

and more particularly a horizontal ventilating unit for installation at the outer end of the drain pipe section of a water system.

An object of the invention is to provide such a unit which may be fitted with testing means for first filling the system with water or oil, and then draining the same, and adapted after such'testis made, to be given a smooth interior surface with a drop, so that no sediment may be: caught therein. As is well known, most municipal ordinances, as to drainage systems, require that such unitsbe provided with such a drop and such a smooth surface that there can be no recesses for the lodgment of sediments. The present invention is especially intended for use in conjunction with a house drain pipe,

the fitting being used as afresh air unit- 7 after the test, but in localities where the law does not require that a house trap be used,

. the same maybe employed asa clean out.

A further object and advantage is to provide for the ready removal of any stoppage which may occur between the fitting and the main street conduit, and which under ordinary circumstances would necessitate digging up of the street. V YVith these and other objects in view, my invention is shown in the accompanying drawings, and will'be hereinafter more fully described-with reference thereto, and finally pointed out in the claims.

"In the accompanying drawings:

ticularly'. to Fig. 1. thereof, my invention comprises 'a unit, the character of which mightf'be termed generally a horizontal T, andconsisting of a horizontal pipe portion 10, providedsubstantially near one end with an upwardly extending pipe portion 11 having a hub12'. The inner end of the horizontal pipe is raised from the main portion 10, sothat its ax s is above the axis of said main portion EtIlCllS sllghtly larger in diameter than the said main' portion, being prov ded at its end witha hub 13. Interiorly the said inner end of the horizontalpipe is threaded as at 14, adjacent the junction of the upright pipe 11. The next adjacent length of pipe 15 of the water system is calked into thehub 13 in the usual manner, this pipe being of an equal diaineterwith the mainv portion 10 of the testing unit.

For making the test a screw threaded plug or bushing 16 provided with a pipe 17 formed integral therewith, the pipe being closed at its end, and having an upwardly extending tap 20, is inserted into the fitting through the upright pipe 13 which is of sufficient diameterto permit this, and is screwed into the interiorly threaded end by means ofa suitable rod successively engag-f 7 ing theholes 18 provided. in the end of the pipe-1j7, and turning in the direction of the threads. An upright pipe 21 is screwed intothe tap 20, being provided with 'a'valve 22 extending atone side and having a pipe 23; thereon directed back into thefitting. Above the Valve 22 a second valve 24 is provided. The valve 24 isfirst openedfthe valve 22 being closed and water is then run into the plumbing system filling the pipes,

whereupon f the usual examinations are made to determine whether the same is faulty. After the test is complete the valve 22 is closed, the valve 24 opened and the Waterin-the system permitted to run out through the fitting. When the test is completed, "the testing device is removed and'a ring or thimble 25 (Fig.2) is'screw'ed into the threaded portion of the fitting.

This ring ispreferably formed of brass, so as to permitits ready removal at any time required, has an interior diameter equal to that of the pipe 15, and the, portion 10 of the; fitting, and is ofsuch length as to fit tight against the end ofthe pipe-15 at one end, and'toform continuous surface with 1 a the interior of the fitting at the otherend.

The connection of the different units, as

no possibility of sediment lodging in the pipe. When my improved fitting is used in conjunction with a house trap, the same serves after the test as a ventilating T by calking the usual fresh air pipe extending and thereby clogging it,

modified formof testing device 26. This to the exterior of the building, into the hub 12. lVhen no house trap is necessary a ferrule provided with a removable plug is secured in to the hub 12 of the fitting, and thesame servesv as a clean out. 1

In Figs. 8 and l, I have shown a slightly device is provided at its inner face with a strainer 27, and at the outer endthe pipe portion is provided with a removable plug;-

. r 28, having diagonal sides which'permits the insertion of the pluginto the fitting, by means of a ratchet wrench. lhe strainer serves to prevent any foreign substances, such as lumps of solder, grit, pieces of cement, etc., which invariably get into the pipes during the building operation, from entering the testing fitting during the test,

These tests according to the size of the building, last from one or two days to more than a week in some cases, so that in cold weather because of the unheated condition of the buildings, the water is apt tofre'eze in the pipes over night. 7 To obviate this the plug 28 may be removed at night permitting all of the water with the exception of a small amount in the lower portionfof the lower pipes to be drainedoff. V a V p 7 7 All. connections it will be understood, may be either calked or screwed, by providing either a hub or screw thread for the amen ment of other units. InFig. 3 I have shown the, upper end of the pipe 11 interiorly' threaded as at 80. Should any stoppage occur in the system at arpoint between the house andthe street pipe, which would be beyond the reach of the ordinary means,

such as wire for opening such stoppages, and would ordinar ly requlrediggmg up of the street, the fitting may be used as a cut ofi for the house system above the same,

A force pumpmay thenbeapplied'to theportion 12 and any 'ing an upright pipeiportion, pipe portion extending horizontallytherefrom in one dio n rection,l and having the bottom interior 'sur- 1 9 stoppage in the'pipe will be forced'out.
